The '66-'70 Falcon is a nice car, too. But, about 300 lb heavier than the early ones. The '66-70 have std trans, too.
Curiously, in '78 I had a '67 Cortina (English Ford) the front end of the Cortina, is a scaled down '66 Falcon. Makes me like the '66 Falcon more.

You should probably add at least 350 lb to these numbers for a FE and 9" rear.
